refactor(smccc): move debugfs to vendor el3 calls

Move debugfs to Vendor-Specific EL3 Monitor Service Calls.
Function Identifier for Vendor-Specific EL3 Monitor Service is '7' and
allocated subranges of Function identifiers to different services are:

0x87000000-0x8700FFFF-SMC32: Vendor-Specific EL3 Monitor Service Calls
0xC7000000-0xC700FFFF-SMC64: Vendor-Specific EL3 Monitor Service Calls

Amend Debugfs FID's to use this range and id.

Add a deprecation notice to inform debugfs moved from arm-sip range to
Vendor-Specific EL3 range. Debugfs support from arm-sip range will be
removed and will not be available after TF-A 2.12 release.
